WebRadium D and radium E are the historical names that Ernest Rutherford used for lead-210 (Ra D) which has a 22-year half-life, and bismuth-210 (Ra E) which has a five-day half-life. Since lead-210 and bismuth-210 are always accompanied by polonium-210, which Rutherford called radium F, such a source is almost always described as Ra DEF. WebBismuth-209 has a half-life of roughly 19,000,000,000,000,000,000 years. Jefferson Lab, U.S. Department of Energy ... 209 Bi is bombarded with neutrons in a nuclear reactor to form radioactive 210 Bi. The 210 Bi (with a half-life of 5 days) decays via the reaction 210 Bi→ 210 Po+β ...
